BERNARD GOHRBAND, or CHICAGOJLLINOIS, AssreNoR are E. GOLDMAN & COMPANY,OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

BOTTLE-WASHER BRUSH.

To all whom it may concern:

Be it known that I, BERNARD GOHRBAND, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented anew and useful Improvement in Bottle Washer' Brushes, of whichthe followin is a specification.

My invention re ates to an improved construction of the brush deviceused for scouring the interiors of bottles subjected to the cleansingaction of a bottle washing machine, such as that set forth in LettersPatent of the United States No. 7 68,492, dated August 23, 1904, inwhich such brush devices are shown and described.

The ob'eet of my invention is to provide improve means for connectingthe brushhead or brush proper'with the upper end of the vertical s indlewith which it is used on a machine of t e kind referred to and which isrotated axially and reciprocated intermittently to introduce the brushinto a bottle to be scoured, brought into registration with it by theaction of the machine, and to withdraw it therefrom after it hasperformed its scouring function.

In the accompanying drawings, Figure l is a view in elevation, exagerated beyond actual size, of a brush device embodying my improvementand Fig. '2, a perspective view, also exaggerated beyond'actual size,showing the parts involved in In improvement in disassociated relationrea y to be assembled for fastening the brush-head to a socket which isada ted to be fastened on the upper end of a bros -spindle.

A is the brush-head, comprising brush fiber I B and a stem C, on which te bristles are fas tened. The stem is formed of lengths of wire, ofwhich two are shown, twisted spi rally together, and the bristles aredisposed between the spirally-twisted wires. Between the ends of thebrush-fiber it is bound, as by wire, at a about the stem to contract theupper section into a narrower bunch I), resentmg the bristles at sharperan les to t e stem for scourin the interior of t e bottom of a bottle, we the lower bunch I) is more expanded, having the bristles extendingmore nearly perpendicularly to the stem for scouring the inner surfaceof the bottle-wall. The wires at the lower end of the stem are bentoutward in diametrically o posite directions at right angles to the be yof the stem to Specification of Letters Patent. hpplicatlon filedDecember 4, 1905.

form a species of cross-head c, by which to secure the brush-head inplace, as hereinafter described.

D isan internally-threaded socket or head adapted to be screwed upon theu per end of one of the aforesaid rotatable an reciprocable spindles(not shown) of a bottle-washing machine. The u per end of the head D isprovided with a d iametrical recess d and has extendin from it anexternally-screw-threaded neck T), split longitudinally to divide itinto two similar sections separated from each other by a slot dcoincident with and of the transverse width of the recess d, the innersides of the sections containing central longitudinal grooves d d toreceive the twisted stem C. At E is represented a collar or nut adaptedto screw upon the neck D.

To assemble the parts, the stem is adjusted on the head D by introducingthe cross-head 0 through the assage or slot (1 to seat the cross-head int e recess d, whereby so much of the stem as is contained between thesections of the neck D is'centered by entering the grooves (1 Thereuponthe nut E is screwed upon the neck against the stem ends 0 in the recessd, thereby clampin the stem in place. The confinement of t e brushheadon the spindle, of which the socket D forms. an end, is thus renderedsteady and firm, and the construction facilitates adjustment of theparts together and their separation.

What I claim as new, and desire to secure vided in its top with a recessand-havin a slotted neck extending from it through which to insert thestem and enter the cross-head in saidrecess, and a collar on said neckclamping said cross-headin said recess, for the purpose set forth.

2. In combination, a stem provided on one end with a cross-head, brushfiber securedto the stem toward its opposite end, a head provided in itstop with'a recess and having a slotted externally-threaded neck extendinfrom it through which to insert the stem and enter the cross-head insaid recess, and a nut screwed upon said neck and clamping saidproslsl-head in said recess, for the purpose set ort Q meme 3. Incombination, a stem composed of at opposite sides of the slot therein,and a re spirally-twisted wires formed into a crossnut screwed upon saidneck and clamping head at one end, brush fiber confined besaidcross-head-insaid recess, for the purpose tween the twisted wires of thestem toward set forth.

its 0 osite end a. head adapted to be conmeets; at its lower end with aspindle and BERNARD GOHRBAND' provided in its top with a recess and witha In presence of-- slotted threaded neck extendin from said M. S.MACKENZIE,
